Construction & Real Estate: embodied carbon and jobsite emissions under control, with CarbonOS.

Carbonova brings construction site emissions (diesel, generators and power), purchased material quantities and EPDs, and the energy use of operating buildings into CarbonOS, a platform of AI agents. It calculates embodied and operational carbon per project and per asset, compares material and retrofit options by their effect on cost and CO₂, and produces reports with an audit trail back to the invoice or the meter.

They come from two places: operational carbon, from the energy used to heat, cool, light and run buildings, and embodied carbon, from materials, transport and construction work. Together, buildings and construction account for 34% of global CO₂ emissions, and the sector depends on materials such as cement and steel that are responsible for 18% of global emissions (UNEP, 2025). That is why material choices matter as much as building efficiency.

Under the recast Energy Performance of Buildings Directive, which Member States had to transpose by 29 May 2026, new buildings must be zero-emission from 1 January 2028 if owned by public bodies and from 1 January 2030 for all others. Life-cycle global warming potential, embodied carbon included, must be calculated and disclosed in the energy performance certificate from 2028 for new buildings over 1,000 m², and for all new buildings from 2030.

Since 1 January 2026, EU importers of cement, iron and steel and aluminium must surrender CBAM certificates on embedded emissions, priced at €82.32 per tonne in the third quarter of 2026 (European Commission, 2026), so the carbon in imported materials now has a price. From 1 January 2028, ETS2 adds a carbon price on fuels used to heat buildings and for road transport. Carbonova links material purchases and building energy use to these prices and ranks reduction options by cost per tonne avoided.

The supply chain agent collects supplier EPDs and data, and the planning agent compares options for each project, such as blended cements or scrap-based electric arc furnace steel, by cost and CO₂ avoided. The gap can be large: on global average, scrap-based electric arc furnace steel emits 0.69 tCO₂ per tonne, against 2.34 for the blast furnace route (worldsteel, 2025).

Yes. CarbonOS reads purchase and invoice data from ERP systems such as SAP or Oracle, plus energy meters and IoT data from sites and buildings, and keeps for every value the lineage to its source document, a versioned emission factor and a change history, in line with the ISO 14064-3 verification standard. The same dataset serves regulatory filings, ISSB-aligned disclosures, green finance and requests from investors, tenants and customers.
